#### Introduction to Milling Tools and Their Application

Parts of an Angle. The corner point of an angle is called the vertex. And the two straight sides are called arms. The angle is the amount of turn between each arm. How to Label Angles. There are two main ways to label angles: 1. give the angle a name, usually a lower-case letter like a or b, or sometimes a Greek letter like α (alpha) or θ (theta)

Angle of Projections : Engineering Drawing: We all know that engineering drawing is language of engineers. So every engineer must be able to read drawing ond decode the information provided at drawing. This exercise enables you to identify the projection system and you will never forget.

#### Tools to Measure Angles

An end-mill tool representative of the end-mill tools of the prior art is illustrated in FIGS. 1A and 1B and identified with reference numeral 100.The tool 100 has been formed of cylindrical rod stock which has been ground to form distinctive portions.At one end of the tool 100 is a shank portion 102, suitable for chucking to the spindle of a milling machine (not shown) for rotating and ...

#### End mill

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is …

The reason to choose this plan to start with was the 10 degrees toolbit angle. I like to keep tool overhang low and a lower angle is just fine for this. Also, the higher the angle is, the more unbalanced the flycutter will be. Later have made the smaller one with 27.5mm diameter for 6mm toolbit. On this one the angle used was 15 degrees.

#### different angle of a endmill with drawing

End Mills are used for making shapes and holes in a workpiece during milling, profiling, contouring, slotting, counterboring, drilling and reaming applications. They are designed with cutting teeth on the face and edge of the body and can be used to cut a variety of materials in several directions.
